Chapter 70 The first experiment, live up to the original intention (don't add more for Thousand

"Okay." Ma Zhen activated the prosthesis as requested.

Then, the running indicator lights of the sensing caps light up at the same time.

Chen Shen took out the notebook he carried with him, connected it to the signal of the signal conversion device, and checked the running status of the whole machine.

"There is no problem with the connection between the brain control system and the prosthetic." He turned off the system and looked at Ma Zhen.

"This prosthesis has been tested before you came, and it works normally." Ma Zhen said.

Uncle Wu and his son in the back stretched their necks to watch, full of curiosity about the prosthetic limbs on the table.

"Then let's start the test." Chen Shen stepped aside, beckoned to Uncle Wu, "Uncle Wu, come here and sit down."

Uncle Wu hurried over, sat on the chair and straightened his back. His son also followed him and put his shoulders stiffly.

The test prosthetics were suspended above the brackets.

Seeing the nervousness of the two, Chen Shen put the sensing cap on Uncle Wu: "Don't worry, this is just a simple test."

"Have you ever installed a myoelectric prosthesis before?"

"No, Uncle Wu has no experience of using prosthetics for a long time."

Ma Zhen answered for Uncle Wu, who had carefully asked various questions related to the experiment before.

Uncle Wu in front of him had his entire right arm amputated due to an accident ten years ago, and because of family reasons, he has never installed myoelectric or electric prosthetics.

Around this seaside town, Uncle Wu is already the most suitable experimenter.

"That might be a little troublesome."

Chen Shen was mainly worried that the nerve signals related to Uncle Wu's arm movement would be weakened.

If a myoelectric prosthesis was installed before, the nervous system needs to issue instructions to generate myoelectric signals when using the prosthesis, and this situation will not occur.

"Then what should we do now?" Uncle Wu turned his head and asked.

Chen Shendao: "Try it first and see if you can read your nerve signal, Uncle Wu."

After speaking, he backed away, put his body camera aside to shoot, went back to the computer by himself, and turned on the brain control system again.

"Uncle Wu can start now. Just imagine your right hand moving, reaching out or twisting your wrist." Chen Shen said.

"good."

Uncle Wu agreed and tried his best to do as required.

However, the prosthetic limb on the side bracket has not responded for a long time...

Ma Zhenxin was cold for a while, and turned to look at Chen Shen.

Chen Shen was calm at this time, "Don't worry, this is a normal phenomenon. After all, his right arm has been missing for too long, and it is normal for the signal to be messy."

At this time, Uncle Wu saw that the prosthetic limb hadn't moved for a long time, so he also stopped. He looked at Chen Shen anxiously, not knowing what to do next.

Chen Shen smiled and gave a thumbs up: "Uncle Wu, continue, the current situation is normal, and there will be a turnaround soon."

He glanced at it, and the data on the computer showed that the corresponding nerve signal was still being retrieved. After one retrieval, the latter signal would be locked, and it could be connected at any time in the future.

Uncle Wu wiped the tense sweat on his forehead with his left hand, and simply closed his eyes to continue. His son was also cheering him on with his eyes.

Everyone in the team looked nervously at Uncle Wu on the chair, and all the sleepiness just now was thrown into the sky.

Ma Zhen was nervously snapping his fingers, making a crackling sound...

squeak~

Sudden.

There was a soft click on the prosthesis.

I saw that the prosthetic limb that hadn't moved just now was activated, and the five fingers slowly tightened into a fist.

Uncle Wu stared blankly at the prosthetic limb that was moving according to his own wishes...

call!

Everyone's first reaction was to breathe a sigh of relief, and then they felt the joy and sense of accomplishment welling up in their hearts.

Chen Shen looked at the computer screen, which showed that a signal that was suspected of making a fist had been matched, and if there was a mistake, he could correct it manually.

"Uncle Wu, did you just imagine yourself clenching a fist?" He asked Uncle Wu who was staring blankly at the prosthesis.

"Oh!" Uncle Wu's eyes regained focus, and tears gradually poured out, "Yes, I was imagining myself clenching a fist."

Chen Shen nodded, that means there is no match error in the signal.

"Go ahead," he said.

"Okay!" Uncle Wu wiped away the hot tears that poured out unconsciously with his left hand, and wanted to continue the test, but his palms were all wet, and the tears couldn't stop.

The person next to him immediately brought a tissue and asked Uncle Wu's son to wipe his father's tears.

In such a situation, the experiment obviously couldn't go on. Chen Shen shook his head with a smile, suspended the test, and waited for the father and son to calm down before continuing.

The person next to him brought water glasses to Shen Chen and Uncle Wu.

Ma Zhen grinned and opened his mouth, but couldn't close it at all.

Not only him, everyone at the scene had smiles on their faces, even Chen Shen was no exception.

They feel like they are doing something meaningful and worthwhile.

The meaning and value of this matter are not only fed back to them, but can also be passed on to others through them.

Maybe they gritted their teeth and persisted in the past few years just to make themselves and others smile like this.

After taking a sip of water, Uncle Wu came over and thanked God Chen with endless words.

Chen Shen hurriedly asked him to calm down and prepare for the next test.

"Okay!"

Uncle Wu sat back on the chair excitedly, feeling that his heartbeat had been speeding up and couldn't stop at all.

"The second test will be done next, matching the movements of wrist rotation and elbow flexion and extension." Chen Shen reminded.

Uncle Wu was full of passion and was very cooperative in imagining these actions.

Soon, in less than a minute, the wrist rotation signal was detected and matched.

The mood of the people at the scene has calmed down, but they still couldn't help but applaud in unison.

After that, the flexion and extension signals of the elbow were quickly matched successfully.

Seeing Uncle Wu joyfully controlling the prosthetic limb on the bracket like a child who got a new toy, everyone felt relieved, as if a spring of warmth gushed out from the bottom of their hearts and spread throughout their bodies.

Live up to your original intention!

The test could be over at this point, but everyone looked at Uncle Wu's joy, and no one could bear to disturb him.

It wasn't until half an hour later, when Uncle Wu realized that there were fewer and fewer people around him, that he realized that the experiment had stopped, so he stopped embarrassingly.

"It's okay, Uncle Wu, you can continue the test, let's collect more data." Ma Zhen said while sitting in front of the computer, as if analyzing the data.

In fact, he is now discussing with Chen Shen what needs to be improved on the prosthesis.

"Current prosthetics still have some actions that cannot be performed, and the execution time of the actions is still too long, and the fingers cannot move independently. Our first-generation products must achieve the fastest action execution time within one second, and allow multiple actions. executed simultaneously."

"Hmm..." Chen Shen thought for a while: "Let's put it this way, in the first generation of products, I require users who use our prosthetic limbs to be able to type on the keyboard with the same sensitivity as a normal person."

When Ma Zhen heard this goal and thought about it carefully, his scalp felt numb.

"Keep working hard and come to me if you have any problems!"

Chen Shen patted him on the shoulder, retracted the camera and left.

Of course, before leaving, he also asked Uncle Wu if he could put the video he just shot on the Internet, and he got a yes answer without a doubt.
